WILLIAM II. THAYER, OF CHICAGO, ILLINOIS.

SELF-GENERATING GAS-TORCH.

To all whom it may concern.'

Be it known that I, WILLIAM II. THAYER, a citizen of the United States, residing at Chicago, (Rogers Park,) in the county of Cook and State of Illinois, have invented a new and useful Improvement in Self-Generating Gas-Torches, of which the following is a specification.

My inventionrelates particularly to torches for use in preliminarily heating the retorts of self-generating gas-lamps- My primary object is to provide a self-generating gas torch which shall be economical in operation and well adapted to the purpose of preliminarily heating the retorts of selfgenerating gas lamps.

The invention is illustrated in its preferred embodiment in the accompanying drawing, in which- Figure 1 represents a perspective view of my im roved self-generating gas torch, said view s owing, in dotted lines, the generator of4 a self-generatin gas lamp adapted to be heated by means o my improved torch; Fig. 2, an enlarged sectional view taken as indicated atv line 2 of Fig. l Fig. 3, an enlarged broken sectional view taken as indicated at line 3 of Fig. l and Fig. 4, an enlarged lroken section taken as indicated at line 4,

In the'preferred construction, the device comprises a tubular handle A adapted to serve as a main oil-chamber, said tubular member ybeing equipped at its upper end with a cap a iitted with a removable plug al; a feed, or measuring device A1 mounted in the upper end of the member A and communicating with an outlet pipe a2 extending at right angles to the pipe A; a generator pipe A2 supported by and connected with the pipe a2 and extending at right angles thereto; a gas tube A3 carried by the free end of the tube A2 and having. a re-curved end a3; a tubular member A4 into which the gas is injected from the member A3; a gas burner A5; and a pair of retortenvfaging arms A projecting from the burner 5 in a direction away from the handle A. The feed device A1 comprises a hollow inverted frusto-conical member a, from the smaller lower end of which depends a tube a5 communicating with the inner end of the plipe a2, it being understood that the pipe a2 as tight connection with the wall of the member A through which it passes. The member a, which serves as an oil-hopper, is centered with relation to the pipe A which Specification of Letters Patent.

contains it, and the upper end of the member a4 is separated from the interior surface of the member A by a small annular space als. It will be understood that when the handle A is inverted allowing the liquid to run to the upper end, a quick reversion of the handle will cause'a quantity of oil to be trapped by the hopper a, whence it will feed by gravity into the pipe a2. The outer end of the pi pe a2 carries a `fitting e, through which the pipe a2 makes connection with the pipe A2. The iitting a forms one end of the tubular burner A5 and carries one of the )rongs or rests A The member Alis formed integrally with a fitting a7 which aiiords a cap for the free end of the tube A2 and the free end of the burner-tube A5. The tube A2 communicates through said iitting with the tube A3; and the tubular member A4 communicates through said fitting with the burner-tube A5. The burner-tube is provided on its upper surface with a series of rows of perforations (L8, a portion of which are adjacent to the generator tube A2.

B represents the retort of a self-generating gas lamp, and it will be observed that the arms A are spaced a sufficient distance above the burner A5 to receive the retort B between them and the burner-tube A5.

The operation may be explained briefly: When it is desired to preliminarily heat the retort of a self-generatinv gas lamp, a match may be applied to pre iminarily heat the sm all tube A3 after which the implement may be inverted and reverted to get `a supply of oil into the chamber (1,4, whence the oil will feed by gravity to the tube A3 where gas will be formed and injected into the tubular member A4, drawing with it the necessary air to form. a combustible mixture. A match may then be applied to the burnertube A5, and the heat generated at the burnerftube will then sufhce to generate gas in the tube A2, the gas continuing to burn until the supply of oil in theV vessel a is exhausted. The device may then be raised until the arms A are brought into engagement with the generator B of the self-generating gas lamp, whereupon the device may be allowed to remain with the burner-tube A5 beneath the retort B a sufficient length of time to preliminarily heat the retort B. When the generation of gas in the retort B has progressed sufficiently, the gas lamp can be lighted, and the torch may then be employed for lighting other lamps.

I have shown the handle A, provided with an inlet nipple c controlled by a stop-cock, c1. If desired, air-pressure may be applied through the nipple to assist in forcing the oil into the retort.

It may be remarked further that the inclined walls of the vessel a permit the surplus oil to be discharged from the vessel into the reservoir A by tilting the reservoir to a position approximating a horizontal position.

I have shown applied to the member A4 a drip-pan, D, which has an angular extension D1. In lighting the torch, oil is allowed to drip for a moment into the .drip-pan, and a match is then applied. So soon as the gas enters the burner-tube, the flame is communicated thereto from the extension D1 of the drip-pan.

Vhat I regard as new, and desire to secure by Letters Patent, is:

1. The combination of a handle having an oil-reservoir, a tube projecting laterally from the upper portion of said handle, means located above the level of the said tube for supplying oil by gravity feed to said tube, a retort projecting at right angles to said tube, a burner-tube parallel to said retort, and means for delivering gas from the retort to the burner-tube and injecting air therewith into the burner-tube.

2. The combination of a handle having an oil-reservoir, a tube projecting laterally from the upper portion of said handle, a chamber located above said tube for supplying oil by gravity feed to said tube, a retort projecting at right angles to said tube, a burner-tube parallel to said retort, a tube projecting'from the free extremity of the retort and having a recurved end, and a tubular member communicating with the free end of the burnertube and having an open end adjacent to the recurved end of the tube projecting from the retort.

f 3. The combination of a handle. having an oil-reservoir, a tube projecting at right angles from the upper portion thereof, a feed device in theupper portion of said reservoir communicating with said tube,l a generatortube communicating with the freev end of said first-named tube, a burner-tube parallel with and adjacent to said generator-tube .and having a plurality of burner orifices on its upper side, arms projecting laterally beyond the burner-tube, and means for delivering gas from the retort and injecting air therewith into the burner-tube.

4. The combination of a handle having an oil-reservoir, a tube projecting laterally from the handle, means for supplying oil to said oil-reservoir, a tube projecting laterally therefrom and extending through a wall thereof, a chamber within the upper portion of the reservoir having an opening at its upper end and having its lower end in communication with said tube, and a burner supplied from said tube.

6. The combination of a-handle having an oilreservoir, a tube projecting laterally therefrom and extending through a wall thereof, a chamber within the upper portion of the reservoir having an opening at its-upper end and having` its lower end in communication with said tube, and a retort and burner supplied from said tube.

7. rIhe combination of a handle having an oil-reservoir, an inverted conical, hollow member in the upper portion of the reservoir A having an opening at its upper end, a tube extending through a lateral wall of the reservoir and in communication with the lower end of said hollow member, and a burner supplied from said tube.

8. The combination of a tubular handle having a removable closure at its upper end, a feed-device having a chamber located in the upper end of said handle, a tube beneath the level of said chamber and projecting laterally from the handle and supplied from said chamber, and a burner supplied from said tube.

9. The combination of a handlehaving an oil-reservoir, a tube projecting laterally from the handle and receiving its supply from the reservoir thereof,.a fitting on the extremity of said tube, a retort-tube and a burner-tube carried by said fitting, a itting carried by the extremity of said retort-tube and burnertube having a tubular member communicating with the burner-tube and having an open end, and a tube carried by said last-named fitting and in communication with said retort-tube and having a recurved end, for the purpose set forth.
